ARMATURE-BANDING lVIACI-IINE.

Application filed November 10, 1922.

To all "whom it may concern.

it known that I. PHILIP E. HENNIN- can, a citizen of the United States, and a dent of Pittsburgh, in the county of .tllegheny and iltate of Pennsylvania, have invented a new and useful Improvement in \1'11ElTUIP-Bttl'ldlllfi Machines" of which the owing is a specification.

My invention relates to banding machines, more especially to machines adapted to band armatures for dynamo-electric machines and maintain a uniform tension on the banding material.

it is among the objects of this invention to provide a banding device which shall be capable of handing armatures or like ohjots in an expeditious and uniform manner. which shall be of simple and inexpensive construction, and which shall be automatic in its control of means for providing proper tension and feeding of the banding material.

ivl y present device comprises a stationary support or bed adapted to rotatably support an armature to be handed and pro vided with a feeding device which assures a rate of feeding the banding material equivalent to the peripheral speed of the armature. For this purpose l provide a guide-wheel which is directly connected or secured to the spindle by which the object to be handed rotated and the size of this guide-wheel is the same as the surface to be handed. The guide-wheels may readily be attached to the driving spindle or any suitable part of the machine and may be available in sets corresponding to the change gears commonly employed on machine tools.

In the accompanying drawing constituting a part hereof and in which like reference characters designate like parts Fig. 1 is a side elevational view of a banding machine embodying the principles of my invention, and

Fig. 2 is an end elevational View thereof.

The device consists of a stationary support or bed plate 1 mounted on suitable pedestals 2 and provided with a head-stock 3 having a driving spindle a journaled therein which is adapted to be actuated by a suitable driving mechanism (not shown). The head-stock 3 is provided with a face plate 5 and a center 6 on which a rotor 7 such as an armature, is mounted for rota- Serial No. 600,179.

tive movement. The other end of the rotor '7 may be supported by a tail-stock (not shown) having a center to engage the recess 8. A plurality of guide rolls 9 are mounted. upon the bed plate 1 by means of suitable brackets 10, and a sheave 11. is pivotally mounted on the end of a piston 12, which is mounted in a cylinder 13 securec underneath the bed plate 1. The cylinder 13 is connected, by suitable conduits 14, provided with a gauge 15 and a plurality of valves 16, to a suitable source of liquid pressure such as air, water or oil by which the piston 12- is actuated.

A feed wheel 18 having a straight or tapered groove or face 19, which is of the same circumference or diameter as the armature 7, is mounted on the spindle d by se curing it to the face plate 5 in any suitable manner, as by bolts 20.

it suitable banding material, such as a wire 22 is taken from a supply reel (not shown) which may be mounted on the bed plate 1 in the plane of the feed wheel 18 upon which several turns are wound and from which it is extended around the guide wheels 9, the sheave wheel 11 mounted on the piston 12, and thence to the armature on which it is wound.

The feed wheel 18 functions to feed the wire 22 at the same rate of speed at which it is wound around the armature 7, inasmuch as both the wheel 18 and the armature 7 are mounted on a common spindle and are of the same diameter. The piston 12, upon which the wire is supported by passing around the sheave wheel 11, functions to provide a uniform tension on the banding material b means of a uniform pressure exerted on the piston which is controllable by means of the pressure'gauge 15 and the valve 16. The conical shape of the groove 19 in the feed wheel 18 and the several turns of wire wound therein provides a gripping action and is instrumental in effecting an initial tension on the wire between the source of supply and the piston 12, respec tively.

It is evident from the above description of my invention that it constitutes a simple and efficient means for handing armatures or other light rotating bodies and that such banding is accomplished in a simple and expeditious manner. The feed Wheel 18 is considered a decided improvement over the prior art which did not provide for the feeding of the Wire independently of the rotor or body upon which it was wound.

.ilthough I have described a specific embodiment of my invention, it will be obvious to those skilled in the art that various modifications may be made in the details of construction. F or instance, the feed wheel need not be mounted on the main re spindle of the banding machine but may be journaied on an independent shaft geared to or otherwise driven by the driving spindle or an independent source of power. The liquid-pressure-actuated tension member may be automatically controlled by suitable checlr valves or other means well shown in the art and the general design and construction may be modified to accommodate some particular condition of use. These and other changes may be made without departing from the principles herein set forth. Q

I claim as my invention:

1. A. banding machine comprising a base adapted to rotatably support an object tobe handed, feeding means adapted to feed the banding material at a speed corresponding to the peripheral speed of the rotating object and means for regulating the tension of said material.

2. A banding machine comprising a base adapted to rotatably support an object to be banded, feeding means adjacent to said object adapted to feed the banding material at a speed corresponding to the peripheral speed of the rotating object and means for regulating the tension of said material.

3. A banding machine comprising a base adapted to rotatably support an object to be banded, feeding means adjacent to said object adapted to feed the banding material at a speed corresponding to the peripheral speed of the rotating object and means for automatically regulating the tension of said material.
